EN 81-20 denes the technical requirements for lift construction.
EN 81-50 provides the framework for design and testing of lift components
6.3.2 Safety specication
Safety outputs 13-14 and 23-24
Safe state of outputs Open
Safety inputs S12-S11 and S22-S21
Safe state of inputs Open
Safety function
1. The release of either one or both safety inputs will release the safety
outputs.
2. The re-activation of the safety outputs is only possible after the release
of both safety inputs.
6.3 Technical data
6.3.1 Timing specication
Activation time Ta < 160ms
Release time Tr
Double channel mode: < 20ms
Single channel mode: < 160ms
Simultaneity Ts Infinite
Monitored manual start delay Td > 500ms
Information:
• The start/restart command must be installed outside the danger area in a position where the concerned
danger and entire working area are clearly visible.
• It must not be possible to reach the start/restart command from the inside of the danger area.
Attention:
Use in manual start mode is mandatory where the safety device controls an access protecting a danger
zone. This is to prevent a situation in which, once a person has passed through the opening, they could
remain in the danger zone without being detected. Failure to comply with this rule may result in serious
risks to people exposed.
